Composite human physiological stress index based on heart beat and sleep and/or activity history data including actigraphy
First Claim
1. A method for determining a composite stress index for an individual using a computer, the method comprising:
- providing heart beat data at the computer the heart beat data representative of the individual'"'"'s cardiac activity during the time interval of interest;
determining one or more cardiac parameters based on the heart beat data, each cardiac parameter associated with a corresponding characteristic of the individual'"'"'s cardiac activity during the time interval of interest;
determining a cardiac stress index for the individual based on the one or more cardiac parameters;
providing sleep history data at a computer, the sleep history data comprising one or more sleep onset times and one or more awakening times for an individual during a time interval of interest;
determining one or more sleep parameters based on the sleep history data, each sleep parameter associated with a corresponding characteristic of the individual'"'"'s sleep during the time interval of interest;
determining a sleep stress index for the individual based on the one or more sleep parameters; and
determining a composite stress index based at least in part on one or more of the cardiac stress index and the sleep stress index.

Abstract
Systems and methods are provided for providing a composite stress index representing a quantified stress level that an individual may be experiencing or may have experienced during a time interval of interest. The composite stress index is determined based on a combination of heart beat data representative of cardiac activity of the individual during the time interval of interest and one or both of: sleep history data comprising one or more sleep onset times and one or more awakening times during the time interval of interest; and physical activity history data representative of gross motor activity of the individual during the time interval of interest.
